There's a 7/10 game buried in this travesty of a port. I've beaten it 2 or 3 times on PC. I didn't know a cartridge game could have this much slowdown - it's as if you're playing on a single speed CD-ROM and it loads the map before every step that you take. The only good things I can say about this version is the box & manual artwork is much better than the PC version's and I really like the bank's theme (so much so that several times I would just let the music loop for about 10 min).
If you ever decide that you must play this version, do yourself a huge favor and hunt down an SNES mouse (I found a used copy of Mario Paint that had one bundled in with it).
